Stability testing of cosmetics

Stability testing of cosmetics is an extremely important stage in assessing the quality of a product to be marketed in Europe and the UK. W MPR Labs we carry out ageing tests for cosmetics and stability and compatibility tests for cosmetic productsto ensure their safety, efficacy and compliance with the manufacturer's declarations throughout their shelf life.

Inadequate stability can lead to changes in the fragrance, colour, texture and even the performance of the cosmetic. Therefore, cosmetic stability test is essential to maintain the high standard of the product and its positive perception by the consumer.

Cosmetic stability test - what do we check?

Our services include comprehensive stability testing of cosmetics, comprising:

• evaluation of physico-chemical changes under different storage conditions,
• tests at room temperature, elevated temperature, low temperature and under UV light,
• ageing tests for cosmeticswhich simulate the product ageing processes at an accelerated rate,
• observing changes in colour, odour, pH and consistency.

These tests make it possible to assess how a cosmetic will behave during transport, storage or in-store exposure.

Cosmetic compatibility testing with packaging - safety in practice

Cosmetic compatibility test with packaging is an integral part of the overall stability process. At MPR Labs, we analyse whether product components react with the packaging material, whether substances migrate, discolouration or damage occurs.

This is a guarantee that your cosmetic will retain its properties throughout its declared lifetime.

Why are stability tests for cosmetics so important?

• enable a realistic shelf life to be determined,
• minimise the risk of complaints and financial losses,
• ensure compliance with EU and UK legal requirements,
• influence a positive assessment during audits and inspections.

Professional stability and compatibility testing of cosmetic products carried out by MPR Labs means you can be sure that your product will reach your customer in impeccable condition - regardless of transport or storage conditions.
